Trouble with Nested TOCs in DocFX for Generated Content

[dadaPipes]

I am encountering an issue with nested TOCs in DocFX for generated content.
assert/ is where the generated content is.

Works with no problems:

- name: Docs
  href: docs/
- name: v3
  href: v3-1.0.0/assert/

This does not work:

- name: Docs
  href: docs/
- name: v3
  href: v3/
  items:
    - name: v3-1.0.0 
      href: v3-1.0.0/assert/

When I --serve, then I get the following warning:
../Docs\toc.yml: warning: Unable to find either toc.yml or toc.md inside v3/. Make sure the file is included in config file docfx.json!

When I navigate to the content it looks like this:

Never mind.
